Sending Files in Custom fields

From SmartWiki

The File ID field on a workflow task will now allow File IDs for files in a Smart Folder, as well as custom field ids for Single File, Multiple File and Display Only - Image custom fields. The format will be 123456 for the File IDs and @#customfieldid#@ for custom fields. The items are still separated by a semi colon. The workflow task can only send custom field files that are on the object that triggered the workflow.
